SRAM to FX2LP for Memory Expansion

Last Updated: June 19, 2011
Question: 

How can I wire an SRAM to the FX2LP device for memory expansion. Please provide a pin to pin connection detail.

Answer: 

Following is how the SRAM needs to be wired to the FX2LP device. Please use the pin assignments as shown below:

SRAM to FX2
==========
CE# to CS#
OE# to OE#
WE# to WR#
D[7:0] to D[7:0]
A[15:0] to A[15:0]

GND to GND
VCC to VCC

The above is a very standard method of memory expansion on any 8051 microcontroller
